CMake and importing QML files

Oen44

Hi,

I'm trying to figure out a way to have importing work in a more dynamic way than throwing every single .qml file and folder into CMakeLists.txt.

Example project structure:

project/
├── src/
│   └── main.cpp
└── ui/
    ├── panels/
    │   └── RoundedPanel.qml
    ├── buttons/
    │   ├── Button.qml
    │   └── RoundedButton.qml
    └── root.qml

Results in:

import ui.panels
RounedPanel {  }

import ui.buttons
Button { }
RoundedButton { }

The catch here is that if at any point I would create new directory in ui and add new .qml there, it should automatically work (even if after build/reconfiguring CMake).

So far I only came across qmldir (which didn't even work for me) and qt_add_qml_module but that requires manually adding new qml files.

Any suggestions?

I believe globbing is supported by CMake but that it is generally recommended not to use it. As a CMake newbie myself I have followed what seemed to be the prevailing wisdom and stuck to hard coded lists.

One compromise that I did come across was to read the file list from an external file, e.g., file(STRINGS "sources_list.txt" MYSRCS) and then use the MYSRCS variable as your file list in CMake commands (e.g., add_executable(my_app ${MYSRCS})). This would mean maintaining the "sources_list.txt" file externally but that would be easy to automate. I haven't actually tried this though so take all this with a pinch of salt.
